Dry Skin and Moisturizers

Book excerpt: Dry Skin and Moisturizers: Chemistry and Function presents new information relating to skin biochemistry and pathological changes seen in various dry skin disorders. The book examines the pharmacology of ingredients in moisturizing preparations, providing a broad overview of formulations as well as detailed information on ingredients. Featuring contributions from leading researchers from around the world, the book also outlines general principles for testing and evaluation of effects on the skin, with particular emphasis on safety assessment. This comprehensive book is divided into five parts. Part I, Dry Skin and Moisturizers, offers an introduction to this fascinating topic, while Part II, Biochemistry and Function of the Skin, explores everything from particle probes and skin physiology to the distribution and function of physiological elements in skin. Part III focuses on dry skin and hyperkeratotic conditions. Physico-chemical considerations, emulsifiers, hydrophilic pastes, lanolins, and other topics are addressed in Part IV, Formulations and Interactions with the Skin; while safety assessments, human in vivo skin irritancy testing, sensitive skin, and more are examined in Part V, Evaluation and Safety.
